Definitions

  • the invention relates to a sheet metal part for sealed installation between two mutually braceable, provided with essentially flat sealing surfaces components, which is integrally formed with a clamping flange corresponding to the sealing surfaces.
  • Sheet metal parts that are clamped between two sealing surfaces of two components with the aid of seals are used in many ways.
  • a thermostat arrangement for an internal combustion engine which has a basket-like sheet metal housing with a circumferential flange, which we clamped between the cylinder block or head and a connector.
  • the sealing is done by a separate profile seal.
  • the use of an additional, often complicatedly shaped seal is complex and cumbersome.
  • a metallic flat gasket is used Insert between two mutually braced components with flat sealing surfaces known, which carries a circumferential bead in order to achieve a linear seal in the installed state via a residual spring force.
  • the seal is provided on both sides with an elastomer coating, which was applied before shaping, ie the seal is made by molding and stamping a correspondingly coated sheet.
  • this often results in damage to the coating due to cracks and the like, which can cause leaks, and excessive use of coating material. Recycling of the sheet metal waste that occurs during the manufacture of seals is expensive because of the coating on it.
  • the object of the invention is to provide a sheet metal part of the type mentioned, which on the one hand eliminates the need for additional seals and on the other hand ensures a secure seal with minimal use of coating material.
  • the flange is provided with a bead arrangement running all the way around the flange, the area of the sealing surfaces after the shaping of the sheet metal part being elastomer-coated at least on one side and the area outside the sealing surfaces being uncoated, and in that the material of the sheet metal part is so elastic that spring forces result in the area of the bead arrangement in the direction of the two sealing surfaces when clamped.
  • FIGS. 1 and 2 show two mutually braceable components 1, 2, namely a cylinder block or head 1 of an internal combustion engine and a connector 2 having a double connecting piece for two flexible coolant lines, each of which has a flange 3, 4 with flat sealing surfaces 5, 6 have, the flanges 3, 4 can be braced against one another by means of screws (not shown) and accommodate a thermostat arrangement 7 between them.
  • the thermostat arrangement 7 comprises a basket-like sheet metal housing 8, which consists of two basket parts 9, 10, which are connected to one another, for example, by caulking fastening tabs.
  • the basket part 9 facing the connector 2 has two through openings 11, 12, one of which can be closed by an expansion element 13 accommodated in the sheet metal housing 8 with a closure part 14 which can be actuated by the expansion element 13 in accordance with the thermal expansion of the expansion element 13.
  • the basket part 9 has a circumferential flange 15 with screw holes 16, which also extends between the two through openings 11, 12.
  • a bead 17, 18 full bead running around the inside of the screw holes 16 around each through hole 11, 12 intended.
  • the material of the basket part 9 is so elastic, for example spring steel, that in the clamped state in the area of the bead arrangement result in spring forces acting in the direction of both sealing surfaces 5, 6, i.e. that due to the remaining residual spring force of the beads 17, 18 around the respective passage opening 11, 12 on the one hand through the apex of the beads 17, 18 and on the other hand through the beads foot side edges closed sealing lines with the sealing surfaces 5, 6 arise when the basket part 9 is clamped.
  • the basket part 9 is shaped, for example, by deep drawing or pressing and punching out.
  • the basket part 9 is provided in the area of the beads 17, 18 on both sides with an elastomer layer 19 applied after the shaping, which ensures the micro-sealing to the sealing surfaces 5, 6.
  • the elastomer layers 19 are preferably applied by spray coating.
  • the elastomer layers 19 are only in the area in which a seal also takes effect, i.e. in the region of the flange 15, which is clamped between them in the region of the sealing surfaces 5, 6. This not only minimizes the use of the elastomer material, but also avoids the damage to the elastomer layers 19 due to the shape of the basket part 9 after it has been shaped. In this way, the seal is integrated into the sheet metal part, which saves parts and simplifies and simplifies assembly.
  • the sheet metal waste that occurs during the shaping process is easily recyclable due to the lack of a coating.
  • the beads 17, 18 can be connected to one another to form an approximately eight-shaped configuration.
  • the beads 17, 18 can also be designed as half or double beads.
  • the sheet metal parts can also be oil baffle plates or the like. act.
  • the sheet metal parts can also be housing covers or the like between a sealing surface of the associated housing and a ring. Component are clamped.
  • the elastomer coating applied at least on one side usually has a thickness of approximately 10 ⁇ m to approximately 100 ⁇ m, in particular approximately 20 ⁇ m to approximately 50 ⁇ m.
